Title: Improvements in or relating to a.c. measuring devices
Inventor: WALL PETER KENNETH
IPC: G01R19/22
Filed: 1951-11-30
Abstract: 684,665. Current measurements. STANDARD TELEPHONES & CABLES, Ltd. Nov. 30, 1951, No. 28151/51. Addition to 672,099. Class 37. The circuit claimed in the parent Specification is modified so that it operates similarly to a sensitive centre zero instrument over a small range of positive and negative values in the neighbourhood of zero and also will not be overloaded when the measuring circuit is out of balance. The circuit shown in Fig. 1 comprises a Wheatstone bridge having four similar rectifiers 1, 2, 3, 4 arranged one in each arm, and arranged so that a current circulating round the bridge anti-clockwise would bias them all in the forward direction. Input terminals 5, 6 for the current to be measured are connected to a pair of opposite corners 7, 8, the other pair of corners 9, 10 being connected to a centre-zero D.C. instrument 11. The positive terminal of a D.C. bias source 12 is connected through resistances 13, 15, 16, to the corners 7, 8, the negative terminal being connected through resistances 14, 17, 18 to the corners 9, 10. Each of the rectifiers 1, 3 is thus biased in the forward direction with a definite current. Since the corners 9, 10 are connected to the same terminal of the source 12 no bias current can flow through the meter 11. Equal low resistors 19, 20 and equal high resistors 21, 22 are connected as shown. If a small direct current to be measured is supplied to the terminals 5, 6 so that terminal 5 is positive, the blocking of the rectifier 4 is increased and the current flows through the rectifier 1, meter 11, and rectifier 3 to the corner 8. The rectifiers 2, 4 being blocked, the meter 11 is shunted by the resistors 19 ... 22. The current passes through the rectifier 3 in the opposite direction to the bias current. If the current to be measured is increased until it becomes equal to the bias current the resultant current through the rectifier 3 becomes zero and any further increase blocks the rectifier 3 and unblocks the rectifier 2, so that the excess current flows through the low resistor 20 and rectifier 2 to the corner 8. Only a small fraction flows through the meter 11, which is in series with the large resistor 22 across the low shunt resistor 20. If the current to be measured is reversed the rectifier 2 remains blocked the whole time and the rectifier 4 becomes unblocked when the current exceeds the bias current, the meter reading on the opposite side of zero. In a modification, Fig. 3, two similar adjustable resistors 25, 26 shunted by rectifiers 28, 29 are connected in series with the rectifiers 1, 3 to correct for differences in the forward resistances of the rectifiers.

Title: Improvements in or relating to fuel for gas turbine engines
IPC: C10L1/12
Filed: 1951-05-03
Abstract: A fuel for gas turbine engines comprises a mixture of a petroleum residue fraction and a minor proportion of a compound of zinc insoluble in the petroleum residue fraction.  The zinc compound may be zinc oxide or zinc carbonate and may be employed in an amount sufficient to provide up to 3 per cent of zinc, based on the weight of the fuel.  If desired, more than one zinc compound may be used. The presence of the zinc compound materially reduces or prevents the formation of deposits upon interior surfaces of the engine, such as upon the stator and rotor blades.  Corrosion by vanadium pentoxide present in the deposits is also greatly reduced or entirely eliminated.  The petroleum residue fraction may be furnace oil or Admiralty fuel oil. According to the Provisional Specification, an oil-insoluble compound of magnesium may be employed instead of the zinc compound, and magnesium oxide and magnesium carbonate are mentioned.  Specification 689,579 is referred to.

Abstract: 1,170,325. Gunn effect circuits. INTERNATIONAL BUSINESS MACHINES CORP. 22 June, 1967 [13 July, 1966], No. 28794/67. Heading H3T. In an electric circuit comprising two Gunn effect devices 16, 18 with a voltage source for applying a voltage less than that necessary to nucleate a domain across the device, when a signal is applied to a trigger electrode of one of the devices a domain is nucleated and propagated in that device and the current through the other device is reduced such that the formation of a domain in the other device is inhibited. The circuit is biased at a voltage below the turn ON but above the extinction level. A voltage pulse applied to either 44 or 46 raises the voltage across the respective Gunn device 16 or 18 above the threshold level and the device triggered 16 or 18 conducts in its lower current level and a positive-going pulse occurs in the output winding of inductor 26. The inductor winding 36 is coupled to inductor 26 so as to have an opposite negative going output induced in it. This causes the voltage across and current through device 18 to fall so that it cannot be triggered into the high voltage or same state as the other device 16 whilst it remains in its high voltage state. The circuit produces a lengthen output pulse (S1 or S2, Fig. 4, not shown). The Gunn effect devices may be of n-type GaAs or InP.
